Screening Chinese A-Shares by Turnover and Recent Limit-Ups

Summary

This note describes a Chinese A-share stock screen that selects shares with turnover between 3% and 12%, excludes Beijing-listed stocks, and requires at least one limit-up event in the past month. The proposed rationale is that a recent limit-up may signal market attention or momentum, while the turnover band narrows the candidates. The text also suggests checking indicators such as RSI or KDJ and reviewing limit-up stocks more carefully before investing.

No performance tests or historical results are provided. The note cautions that the screen relies heavily on sentiment, can miss company fundamentals, and does not account for the chance that a limit-up stock will retreat. Its sample implementation has apparent data and logic mismatches, so it should not be treated as a validated, ready-to-run strategy. The selection rules are best understood as a starting point for research, with further checks and testing needed before trading.

Key ideas

• The screen requires turnover between 3% and 12% and excludes Beijing-listed A-shares.
• A candidate must have recorded a limit-up event within the preceding month.
• The note associates recent limit-ups with attention and possible momentum, but provides no evidence that they predict returns.
• Sentiment dependence, fundamental omissions, and post-limit-up pullbacks are identified as risks.
• The sample code and selection description contain inconsistencies that warrant validation.
